if(isset($_GET['email']) && isset($_GET['password']) && ($_GET['password'])!='' && $_GET['email']!='')
{
require_once 'connect.php';
$em = $_GET['email'];
$pw = $_GET['password'];
$sql = "SELECT * FROM user_accounts a, user_info ui WHERE email='$em' and password='$pw' and a.userid=ui.userid";
$result = mysqli_query($conn, $sql);

if(mysqli_num_rows($result) != 0){
$row = mysqli_fetch_row($result);
session_start();
echo 'Authorized';
$_SESSION['Authorized'] = 'Granted';
$_SESSION['fullname'] = $row[7]. " " . $row[6];
} else{
echo "Invalid email or password.";

if(mysqli_num_rows($result) != 0){

should be

if($result->num_rows != 0){ ...

I believe.

Well, what's the error message?

You should try to check the return of your mysqli_query function (returns false in case of error)
You can also try to print your result with this code snippet for example, to see if the result is what you expect

echo '<pre>';
print_r($result);
echo '</pre>';

The error is Fatal error:Can't Use function return value in write context in (directory).

I would try both of your suggestions

Not an answer to your problem, but I'd suggest you asking on Stack Overflow or similar. There's a shitton of users willing to help.
Also, put your code in code blocks, make it look nicer. And please say what error you get, or else it can be hard helping you.

@DoomedBlocks
Your code:

if(mysqli_num_rows($result) != 0)

Spit the line into two sub-lines, it should somewhat look like this:

$resultvalue = mysqli_num_rows($result);
if($resultvalue != 0);

thats a common error in php versions prior to PHP 5.5
